Last spring, one of the largest credit unions in the country took the acquisition of banks by credit unions to a new level. In a move that's a first for U.S. credit unions, GreenState Credit Union of North Liberty, Iowa, announced that it would buy two community banks at once: Premier Bank of Omaha, Neb., and Oxford Bank & Trust in Oak Brook, Ill. The combined assets of both community banks make the acquisitions the second-largest purchase of bank assets by a credit union to date. GreenState said that it expected to close both deals by year's end, swelling its assets to close to $9 billion.
